The invention provides a space motion mechanism for a ship and ocean engineering structure model pool experiment, which comprises a Stewart parallel mechanism, a hoisting mechanism and a model connecting part, and is characterized in that the Stewart parallel mechanism comprises six telescopic branch chains, an upper platform, a lower platform and a force sensor, a spherical hinge base is arranged on the lower platform, and a spherical hinge is arranged on the spherical hinge base; one end of the telescopic branch chain is connected with a spherical hinge base on the lower platform through a spherical hinge, the other end of the telescopic branch chain is connected to the upper platform through a universal coupling, and the force sensor is installed at the lower end of the telescopic branch chain. The hoisting mechanism comprises a traveling mechanism, the upper platform is installed at the bottom of the traveling mechanism, and the lower platform is connected with the model connecting part. And the lower end of the model connecting part is used for connecting a ship model or an ocean platform model, so that the ship model or the ocean platform model performs six-degree-of-freedom movement along with the lower platform. The requirements for the position and posture of the control ship model can be met, and simulation of the ship in different navigation states is achieved.

    本发明提供一种用于船舶与海洋工程结构模型水池实验用的空间运动机构,包括Stewart并联机构、起重机构、模型连接部件,其特点是:Stewart并联机构包括6条可伸缩支链、上平台、下平台及力传感器,在下平台上设置球铰基座,可伸缩支链一端通过球铰与下平台上的球铰基座连接,另一端通过万向联轴器连接在上平台上,力传感器安装于可伸缩支链的下端处。起重机构包括行车机构,上述上平台安装在行车机构的底部,上述下平台连接模型连接部件。模型连接部件的下端用于连接船舶模型或海洋平台模型,使船舶模型或海洋平台模型随下平台进行六自由度运动。能够满足对操纵船模位置和姿态的要求,实现船舶在不同航行状态的模拟。
